Hi,
i got this comp about 4 months ago, i cleaned off all dust in the CPU, and all was good, Pc runnig fine

then all of sudden my PC hangs some times without any reason..

No pattern, (ie to see if some app is causing this, but no luck there)

The CPU usage is low.



This what I done so far
clean off all dust in the CPU,
Did chkdsk, NO errors,
Did a soft format of the HD,
then a full format using boot and nuke cd
Reinstall windows 2000 and all other programs
Updated all software
Ran antivirus and spy ware check..
Nothing
got my hijack this log review - nothing there

i also checked the event viewer, no errors
tested memory with memtest86 everything passed

But still the pc hangs for no reason

My pc specs
OS Windows 2000 pro
Intel® Pentium® 4
Level 1 (L1) data cache 8 KB
Chip set Intel 865G
mem - 1.5 gb
Hard drive dual-channel Serial ATA, supporting one device per channel
Running windows 2000 with all the update till today

Please help
